When accelerating from a stop, I get a clunking sound from the front end. I took some pics of the sway bar and I think it maybe loose. There is a gap between the bolt between the bar. Is this normal, or can I tighten it with the X on the ground or does it have to be up on a lift to properly tighten?
View 14 RepliesBought an 05 FX4 SuperCab in May - been in shop twice for a "clunking" sound when accelerating from a dead stop. Dealer says it's "operating as intended" and that no damage was being if I continue to drive. I thought it was a rear problem with the limited slip. Dealer says it's the tranny and that Ford is looking into the problem (apparently quite a few are coming back). She runs smooth and shifts fine once she gets going. Just starting from a complete stop feels painfully wrong.
View 14 RepliesI have a clunking sound coming from the rear of my X when I stop and take off. The sound does not happen until the vehicle has been driven for a few miles. After it has been driven, I will get one clunk when I stop. When I take off I will get one clunk as the vehicle starts to accelerate, and another clunk as I give it a little more gas. What could be the cause of this? I do not get the sound when I shift from park to drive, or drive to reverse.
View 14 RepliesI've been living with a mild "clunk" or "bump" in the drive train when I would first begin to accelerate from a full complete stop. It would only happen after a complete stop. It almost felt like it could be normal, but it seemed to be getting worse over time.
At first I thought it was my transmission...but after some internet searching I found some threads talking about the slip yoke on the drive shaft being the cause. In that the slip yoke needs to be pulled apart and re-lubed.
Anyway, I thought I'd post and let eveyone know that after pulling the slip yoke and re-lubing with grease my issue is solved! The "clunk" is totally gone. 100% Smooth now. If has this issue I'd highly recommend re-lubing the slip yoke.

On my 2004 F-150 SuperCrew, all I needed to do was remove the drive shaft at the rear differential (4 bolts, use 12mm 12 point socket or wrench). Then remove the FRONT clamp on the slip yoke boot. Then slide out the rear 1/2 of the drive shaft. Be sure to mark the drive shaft orientation with the rear differential flange and the slip yoke before you remove the drive shaft to ensure you put it back together correctly.
Re-lube the slip yoke, then slide it back together and reinstall the four bolts at the rear differential. Torque spec is 76 ft-lbs. I used Valvoline FORD-LINCOLN-MERCURY moly grease that I purchased at my local AutoZone. You'll also need to install a new band clamp around the rubber slip yoke boot. I got mine from AutoZone.
Here are some links I found with pictures showing how to do this. Both procedures below are on SuperDuties but its basically the same procedure. Just follow my specific details above for the 2004-2008 F-150

Gf's 01 B5 Wagon(tip) has the clunking noise only on accelerating from a stop,does not do it any other time,does it in tip mode as well,tie rod ends,rotors and front brakes were replaced about 2 months ago,could this be a ball joint/control arm issue,I read as much on this in the other threads when I searched,no noise on turning or braking,possible mount issue?
View 2 RepliesI have a noticeable driveline vibration when accelerating from a stop up to 40 m.p.h., after that speed it goes away. I have driven it up to 75 m.p.h. on the highway with no vibrations at that speed. It only does it from 0-40. I have checked the u-joints and driveshaft run-out and all is good. The truck was lifted 6" by the P/O. The pinion angle looks too high to me. (It has 6* shims under the springs).Front u-joint angle is 1/2*, while the rear is 2 1/2* in relation to the driveshaft. If this is the case, wouldn't the vibrations get worse, not better, when speeds increase above 40 m.p.h.? What else to check???
View 8 RepliesI recently ran into the "clunking from the front end" problem with my Excursion. It is 2WD but this might apply to all. I had the clunk under my left foot while driving over a series of small bumps. It was a rapid clunking. One big bump, or things like speed bumps did not produce the noise or feel in my feet. Only rapid irregularities in the road at 35 mph or greater made it happen.
It made me crazy trying to figure it out. I tried everything. Both sets of swaybar links, shock mounts, track bar mounts, made sure brake calipers were tight, you name it. It showed its ugly head every time I hit small bumps in succession at speed. Even tried to re-seat the coil springs but that didn't work! My front bearings made NO noise. There was NO play in them by hand while up on jacks. I had taken them out and repacked them while replacing front brakes. At my wits' end, I went for a "hail mary" shot. I purchased new bearings. Took it all apart, packed the new bearings and replaced.
Low and behold! The damn "clunking" is now gone! So, in short, IF you have a clunking that nothing else seems to fix, just try replacing the bearings even IF you feel NO play in them. I couldn't believe that bearings that felt so tight by hand would be causing such clunking.
2007 Sonata 3.3. Crunching, clunking noise at low speeds, braking or accelerating away from stop lights. Noise disappears at speeds over 25-30 mph. Noise can be replicated by rocking car forward and backward while in park, with engine turned off. Rocking side to side does not reproduce noise. Bouncing car suspension at all four corners does not reproduce noise. Hood open, rocking forward and backwards, noise seems to be coming from behind engine, and with hand on engine motion can be felt. I'm thinking engine mount, but how can I get a good look at it to check?
View 3 RepliesMy 1999 Subaru Impreza Outback Sport recently got new tires. After, I really started to notice clunking noises when accelerating, but they would stop when the brakes were pressed. It is sometimes loud, other times it may be harder to hear. My dad says the car has been doing it for a while now. When I first got the car in 2011, I remember the car would creak repeatedly when slowing down, but it had to be the right circumstances for the vehicle to be noisy when coming to a stop. Now it does the clunking noise (gets faster as the car goes faster) only when accelerating, does not creak or make noise when turning.
View 3 RepliesI've had a front end clunk best felt on the floorboards at very slow speeds on uneven ground. I've read for a month on this site on this issue and have replaced the ball joints and sway bar end links with Moog parts. New shocks also. Well I've improved but its still there. I cannot budge the trac bar bolts with breaker bar. The axle u bolts seemed loose so I tightened them but I'm not sure of the torque specs on them. What are the torque specs on the u bolts and where to go from here?
View 14 RepliesSo i have been noticing a lugging/clunking sound when accelerating from turning.
I say it sounds like that because its almost like when a noob driving is trying to shift and stalls for not giving enough gas. but this is comming from the back and for the longest i thought it was due to the ESP kicking in but i been driving quite calm lately due to blow shocks.
I wish I could get a sound clip but its only when driving. Is that normal? Prolly not but hear something when it engages? I am on a OEM haldex controller atm.
So I can clearly see the track bar clunk in and out about 1/4 inch when the wheel is turned in either direction...guessing its time for new bushings.
What's the latest and greatest on these? or is "whatever they have on sale at summet from moog" is fine?
OEM only? Truck has a 4" lift, stock bar attached to the drop bracket.
I plan on replacing as I have a clunk happening. Thought I'd try here first.
Is there a brand that's better? 1Aauto has OEM. Is there a brand that's better or makes a difference?
Or is a front sway bar end link a front sway bar end link?
I have the CaryT V/ modded B 33" kit installed, and re-torqued after 200 miles. But since the install the EX pulls to the left and I have a clunking in the front end. The alignment shop said they have my alignment "dead nuts", and it must be my tires. Well I replaced my tires and wheels and I still have the pulling problem.
The clunking I believe is coming from the adjustable track bar, the torque wrench only goes to 250 ft/lbs so went to 250 and then tightened a little more. I have no way to measure the 396 ft/lbs in the specs.
I need to replace the rubber axle bumper guards. I have a clunking noise from the left front going over bumps. Troubleshooting I found the left front axle bumper guard is missing, right side is missing chunks and dry rotted. I had a question about how they attach. The one that is missing looks like a rusted bolt snapped off. Is it safe to assume a bolt goes right thru the center of the bumper guard into the frame? Couldn't tell on the right side it is in bad shape. Right front bolt may have sheared off on the bottom and just held in on the top by what is left.
View 5 RepliesWhen I turn the wheels to full lock, either right or left, I hear a clunking sound. Usually pulling into parking spots, into the driveway, etc.....but only going forward, not in reverse. Where do I start?
View 9 RepliesI am currently having a clunking noise coming from the front driver's side when accelerating from a stop or decelerating to a stop. It seems to happen only at low speeds and only on the driver's side. No strange vibrations or noise when turning or when going over bumps. I am thinking strut mounts or possibly trans mount.
View 24 RepliesI have a noise in the front end that is only happening during suspension travel. It is really bad on bumpy roads. I thought it was my sway-bar end links but they are a year old and tight. I have checked the shocks and they are tight. It sounds like a clunking noise. Could the front drive axles be making this noise while not locked in?
View 14 RepliesI have a 2000 ford excursion limited when i drive a loud clunking noise comes from the front end, so i pulled the front passenger tire off and realized what looks like the axle bearing behind the hub assembly is rattling around. What part is that. I am going to post a picture tomorrow in the day light.
View 2 Repliesfirst off my truck is 2001 ford ranger 4x4 with an auto. transmission. when I'm driving around in 2wd, everything is fine...
when my 4wd high is on, and I'm starting from a deadstop my truck makes a weird "clunking" noise in the front end. If I'm stuck in mud or snow, and I give gas it keeps "clunking". where the problem comes from?
My 2005 ford freestyle (fwd) has a creaking noise when accelerating from stop and turning left but not when turning right. It's been there for a while. I had a problem where front left wheel felt loose. Replaced struts no change. Replaced left front wheel ball joint and fixed that awful feeling, but it still creaks.
